l This invention relates to bus or car window construction, and moreparticularly has reference to the inside and outside stops and themanner in which'the window sash is positioned, an object of theinvention being to'provide a construction which will permit the stops tobe easily inserted without interference of the locks and rails, and inwhich outward movement of the stops will be prevented when in theassembled position. A further object is to provide a construction inwhich the stop willbe eifectually and firmly retained in its properoperative position and which atthe same time will have such freedom inits engagement as to permit of, necessary manufacturing tol- 15` Withthe above and other objects in `view embodiments of the invention areshown in the accompanying drawing, and these embodiments will behereinafter more fully described with reference thereto, and theinvention will be nall pointed out in the claims. l y

As the construction, according to the invention, is they same on eachside of the window open- Y, ing, only one side or post ofsaid openingwill 'be shown in the illustrated adaptation of the invention.

1 represents a postjof the window casing, and 2 generallyv denotes theoutside stop which is made of metal. y I

Referring to 'Figures 1, 2, 3 ,andl 6, this .outside stopcomprisesa'comparatively wide member 3 which has a leg 4 abutting thepost, amember 5 that extends inwardly and iswspaced from thev post andis then stepped ush with the` leg 4 and,

abuts the post, as shown at 6, and immediately' beyond the riser 7 ofthe stepped portion isa comparatively narrow member 8 which is integralWith thestop 2 and parallel to the member 3, the spacing between theriser '7 and member 8 forme ing a groove 9, a protrusion 10 being formedat the end of the member 8. The portion 6 extends beyond the member 8and terminates in a lip 11 that is parallel to said member. Y f

This stop is secured to the post, at suitable intervals by screws 12(only one of which is shown) the space between the member 5 andthe postpreferably containing anysuitable packing 173, such as felt, so as toprevent dirt or moisture from entering the vehicle. The window sashglass 14 has its side edges contained and `adapted to function withinfelt channels, as shown at 15, and these channels are backed by a metalretaining strip which. has a portion 16 that extends behind the channel,jand an outer portion 17 that extends along the outer face of thechannel and abuts snugly against the inner surface of the member 3, saidportion 1'7 terminating in a lip 18 that overlaps the outer leg of thechannel and serves to place.

The portion 1671s backed by a spring 19 that is secured by the screws 12to the member 5, so that it will be clear that the felt channel and itsre- Vkeep the vlatter in tainer can be forced toward the post bythrusting the glass 13 toward the post.

The complete assembly of all parts including the inside stop 2O iseffected as followsl:-,

The inside stop is H-shaped, and before it is applied, the inner leg ofthe felt channel is pulled inwardly and the sash positioned by rstplacing one side thereof within its channel, forcing they latter towardthe adjacent post and then locating the other side of the sash withinits channel; the inside stop is then-positioned by rolling one leg overthemember 8, and entering it underneath the edge of the felt channel, atan angle, as shown i in full lines in Fig. 3, the clearance providedbetween the riser. 7 and the felt channel permitting this, and then`rotating it slightly beyond a per- 10G pendicular position, as shown indot-and-dash lines, the felt channel being compressed in this position.At the same time the stop is pushed to-. ward its seat, kand the handpressure released whereupon it assumes the position shown vin Fig.

2.' The felt channel exerts pressure on theouter k end ofthe stoppressing the inner end against-the step 7 about the protrusion l0 as afulcrum. In

this position a. lip 2l on the stopoverlapssaid leg and co-operateswithr the lip linholding the felt channel in place. The dot-anddash linetainer are coniined between the outside and inside stops, and that theinside stop is held in position by the groove 9, the inward thrust ofthe adjacent leg of the channel andthe member 8. VThe movement of thestop, after insertion into place,

by outward rotation, is limited, as the end of the inside leg contactsthe rise '7 andthe middle por'- tion contacts the protrusion 10. Whilescrews or other means are used to prevent the stopfrom coming off andfor holding it in place, this limitation of outward rotation isimportant, as it pre# vents the stop from getting into a non-operatingposition, inthe event that the screws or other means for holding thestop become looseor do not hold tightly; For the purpose of securing thestop *L I have shown drive screws 22 (only one shown screwed' into thepart 6 of the outside stopV and through the part 23 of the inside stop,the heads of the screws impinging against said part 23, as shown inFigure 6.

; The protrusion lOvof the member 8, itwill be observed, minimizes theoutward movementy permitted by the clearances between the inner andouterlegs of the stopY and the member 8 and lip l'l, these clearancesbeing desirable in order to 353" give a reasonably free t of the stop inthe pockets of the outside stop, to give necessary Arnanufacturv ingtolerances, and to hold the stops in a perpendicular position.

In' Fig. '7 I have'shown a modication in which 4:0` the protrusion onthe member 8 is in the form of a bent or curved portion 24.

Referring to `Figures 4 and 5, a modied form of the invention is Shown,in which the outside stop has a comparatively narrow member 25 provvidedwith a protrusion 26 at its end, while the member 5 is spaced from thepost as described but is also spaced from the memberv25 so as to form agroove 27, the inside stop being integral with the parts of the outsidestop just described,

50,- and the felt channel retainer being reversed as compared with theretainer shown in Figures 2,v 3 and 4, with the lip 18 overlapping theinner leg of the channel. s t

, In this modified construction, the same method of positioning the sashis employed, since in this instance, the sash is put in position fromthe out' side of the vehicle instead of the inside, it being merelyVnecessary to pull the outer leg of the' channel outwardly, locate thesash in precisely. the manner heretofore described, and' then to4 roll aseparate comparatively wide member 28'of the'outside stop over themember 25 and force it into the groove'27, this member 28 having a lip29 which' overlaps the adjacent leg of the channel l and co-operateswith the lip 18 to hold the felt` channel in place.

When the member 28 is in the position shown in Figure 5, it is firmlyheld by the groovev 27, the outwardthrust of the adjacent channel legvand 7o the'member 25.

In fact, there is no difference in invention between the structuresshownatv Figures 2 and 5, one

being a reversal of the other, so as to provide for the installation ofthe window sash from the in- .,side or outside of a vehicle.

The spaced portion 5 is not absolutely necessary so long as the grooves9 and 27 are formed in the outside stop for the purpose heretoforeexplained, and therefore the invention is not limited in this respect.

I have illustrated and described preferred and satisfactory, embodimentsof ther invention, but it will be obvious that changes may be madetherein, within the spirit and scope thereof, as defined in the appendedclaims.

Having thus described my invention what I claim and desire to secure byLetters Patent isz- 1.
